ORegen : New Device for Capturing Waste Energy

At GE’s Global Research Center near Munich, Germany, scientists have developed a new waste heat recovery technology called ORegen — which is a device that converts waste heat from exhaust streams generated by equipment such as small gas turbines and industrial processes into usable electricity.This technology can help customers address the challenges of rising fuel costs and the increased demand for more efficient, environmentally friendly power systems and industrial plants.

They have modified Organic Rankine Cycles (ORC) - an old technology which can use lower heat input temperatures.Therefore, heat recovery now offers a great opportunity to conserve fuel by productively using waste energy to reduce overall plant energy consumption and simultaneously decrease CO2 emissions. For example, when an ORegen (Organic Regenerator) unit is joined to GE Oil & Gas’ PGT25 gas turbine, it can provide up to an additional 25 percent more power on top of the output of the turbine itself.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
